Warwick was next in England on June 27, 1460, when he landed at Sandwich with fifteen hundred men. In four days he was before the walls of London, having marched in that time a distance of seventy miles. According to some accounts, the common people so flocked to his standard, that in those four days his force had swelled to forty thousand. The city threw open its gates and joyfully welcomed him, while Henry fled to the north. In the beginning of July the battle of Northampton was fought. The Yorkists gained a complete victory, and took Henry prisoner. Before the fight Warwick issued the command to spare the common people but to slay the nobles, judging the quarrel to be more especially theirs; and it is significant that throughout the Wars of the Roses the proportion of leaders slain far exceeds that in any other war. Up to this time Warwick's conception of the war was merely the natural struggle of the one party with the other for power, using as their means the rude arguments of the time. He still maintained his loyalty to King Henry, and when the Duke of York, after the battle of Northampton, presented his claim to the throne Warwick opposed him, and prevailed upon him to waive it till the death of the king. But naturally such a state of things could not long endure. Warwick, while respecting the person of the king, was fighting against his orders, and so, while professing loyalty, was actually a rebel. Soon the struggle blazed out anew, and in December, 1460, the Duke of York was defeated and slain at Wakefield. Early in 1461 Warwick was defeated in the second battle of St. Albans, but the royalists not taking advantage of their victory, Edward, son of the Duke of York, accompanied by Warwick, marched on London, and was proclaimed king as Edward IV. Soon after the Yorkists gained a complete victory at Towton (1461), the bloodiest field of the whole war. Nearly all the Lancastrian chiefs were slain, Henry's cause was lost, and ere long he was captured by Warwick and lodged in the Tower. The credit of the crowning victory of Towton does not rest with Warwick alone, for he had the help of young Edward, perhaps as great a military genius as himself. Little is known of the details of the fighting, but we are told that wherever the Earl of Warwick was, there the fight raged hottest. [Illustration: York and Lancaster--The White and Red Roses.]
